“If the outlook for the labor market does not improve substantially, the committee will continue its purchases of agency mortgage-backed securities, undertake additional asset purchases and employ its other policy tools as appropriate,” the Federal Open Market Committee said today.

The FOMC said it would likely hold the federal funds rate near zero “at least through mid-2015.” Since January, the Fed had said the rate was likely to stay low at least through late 2014. The Fed said “a highly accommodative stance of monetary policy will remain appropriate for a considerable time after the economic recovery strengthens.”

The Fed also said it will continue its program to swap $667 billion of short-term debt with longer-term securities to lengthen the average maturity of its holdings, an action dubbed Operation Twist. The central bank will also continue reinvesting its portfolio of maturing housing debt into agency mortgage-backed securities.
